Hagen Brothers farms,Goodrich ND | Only use it in the shop with good ventilation. They run fairly clean with kerosene,but the fumes with #1 or #2 diesel are pretty nasty. I have a couple of good oil fired torpedo heaters in the storage shed that have not been used for years,since I got a propane fired model. The only down side to the propane fired heater is that it will still use up the oxygen in a tight shop,and needs a portion of the heat directed at the propane tank to keep it warm enough to produce vapor for the heater in cold weather. |
